Where were you in '62? Our intrepid customizer was working on a '61 Pontiac Ventura when he came across a totalled near-new '63 Riviera -- that top was perfect!
The body is from Moebius, the roof from AMT and custom parts from several kits including an AMT '65 Grand Prix and unnamed '61 and '62 kits as well as the AMT '65 Rivera.
Paint is Tamiya Clear Green over Model Master Sterling Silver basecoat a variety of other fogged colors. Like a real alligator, the colors are not perfectly symmetrical.
